high quality tetrazolium blue-an overview sciencedirect topics
(Using high-resolution, e.g., 900 MHz instruments even skeletal proton signals are distinguishable.) In contrast, the very wide range of chemical shifts in the 13 C NMR spectra of steroids (∼220 ppm, compared to the 10 ppm range in 1 H NMR) enables the signals of all the 18–27 carbon atoms to be resolved and assigned.
The metabolically active bacteria convert the tetrazolium salt into red formazan dye (2,3,5-triphenyl-2H-tetrazolium chloride, tetrazolium red). A number of tetrezolium salts were evaluated as potential substrates for the enzymatic reaction, but p-iodonitrotetrazolium violet, tetranitro blue tetrazolium, and MTT were found to be suitable
6.2.2 Nitroblue tetrazolium. The tetrazolium salts have been used extensively for the detection of superoxide in phagocytes. Nitroblue tetrazolium (NBT) is pale yellow in color prior to reduction by superoxide. The tetrazoinyl radical is generated by interaction with superoxide and disruption of the tetrazole ring, which subsequently dismutates
FRANK A. BARILE, in In Vitro Methods in Pharmaceutical Research, 1997. 2 MTT assay. In the MTT assay, the tetrazolium salt, 3-(4,5-dimethyl-thiazol-2-yl)-2,5-diphenyltetrazo-lium bromide (MTT), is actively absorbed into cells and reduced in a mitochondrial-dependent reaction to yield a formazan product. 19 The product accumulates within the cell since it cannot pass through the cell membrane.
